Delay of rust formation after laser cleaning
Already on the basis of the first test setting it was clear that cleaning with laser was successful for this application. On 12 March 2019, the cleaned square metre was still as clean as it was immediately after cleaning. This demonstrates the success of this cleaning method. It ensures that additional maintenance jobs can be carried out and that nitrogen conditions can be maintained. Moreover, it ensures that the 'oxidizing' catalyst will be present in the tank much later than normal.
Some results of the project (that has been carried out twice in the meantime):
- projects were carried out without incidents or accidents
- projects were carried out without EO exposure for the operators
- the applicability of the laser cleaning technology has been proven for the asset-owner
- an efficiency of approx. 5 square meters per hour was achieved for this manual lasering.
- the site was able to significantly reduce the cost of cleaning its tanks
Of course, there are also points for attention:
- air turbulence in the tank (combination extraction vs. ventilation)
- ergonomic conditions for manual lasering
- still room for improvement in the quality of cleaning
